What is a benefit of a federated database?

• A. Complete dependence on a single database source
• B. No need for data interoperability
• C. Provision of data without additional persistence or duplication
• D. Complex management of multiple autonomous systems

Answer: (C)

A federated database is designed to provide a cohesive view of data that is distributed across multiple autonomous databases or data sources. One of the primary benefits of a federated database is its ability to provide access to data without requiring additional persistence (i.e., creating duplicate copies of the data) or data duplication. This means that the federated architecture allows users to query and retrieve data from different sources while maintaining the original data in its native location. Because the data isn't duplicated or stored in a central location, this approach minimizes data redundancy and ensures that the data remains consistent and up-to-date across all systems involved. This benefit is particularly valuable in environments where data integrity and real-time access to the latest data are critical. This characteristic also enhances data efficiency and streamlines data management processes, allowing organizations to leverage existing databases without the complexities and overhead associated with maintaining multiple copies of the same data.
